Need a new heating and cooling system in Granite Falls? We install furnaces, heat pumps and AC up in the foothills, from downtown to Lake Roesiger, and our Lake Stevens shop is just down Highway 92.








Most heating and cooling systems give plenty of warning before they quit for good. If two or more of these sound familiar, a replacement quote is worth a look.
Most furnaces and AC units around Granite Falls last 15 to 20 years. Past that, breakdowns and wasted energy pick up fast.
When repair bills start stacking up, or one repair costs close to half of a new system, your money usually goes further on a replacement.
If your bills keep climbing while your habits stay the same, worn-out equipment is often the reason. New high-efficiency systems use less energy.
If some rooms are always too hot or too cold, the system may be undersized, worn out or fighting leaky ductwork. We check all three.
A crack lets combustion gases mix with the air you breathe. If we find one during a visit, we’ll show you and talk through safe options.
Hot summer days are rough without AC. Adding central air or a heat pump keeps the whole house cool.
Repair is always our first move. If a fix will keep your system running safely for years, we’ll tell you that before we ever quote a replacement.
Gas furnace and central AC: the go-to setup for Granite Falls homes with natural gas. You get strong, fast heat on cold mornings and central cooling for summer.
Heat pump: all-electric heating and cooling in one system. A Mitsubishi Hyper-Heat keeps full heating output down to 5°F, a strong all-electric choice for foothill homes without natural gas.
No ductwork? A ductless mini-split heats and cools room by room. It’s ideal for cabins, shops and add-on rooms out in the foothills.

It depends on the equipment and your home. As a guide, furnace replacements run about $5,000 to $10,000, furnace and central AC systems about $11,000 to $17,000, and Mitsubishi Hyper-Heat systems from around $16,000, before sales tax. Try the calculator above for your home.
Usually not. Most furnace and AC swaps are done in a single day, so the heat is back on that evening. Bigger jobs like a new heat pump, ductwork or an electrical circuit can add a day, and we’ll tell you before we start.
Foothill homes in Granite Falls see colder nights and more snow than towns down by the Sound, so the system has to be sized for that. We do a load calculation at your home instead of matching the old unit, so the new system heats and cools evenly without short cycling.
Sometimes it is. If the system is under 15 years old and the repair is modest, fixing it usually makes sense. Once repairs approach half the cost of a new system, or there’s a cracked heat exchanger, replacing is the smarter spend.
